Nov. 19, 1929. E. RADEMACHER DEVICE FOR THE PRODUCTION OF SMOKE AND THE LIKE Fxled Jan. 1l, 1927 Patented Nov. y 19, 1929 ERICH RADEMACHER, OF KAHLA, GERMANY DEVICE FOR THE PRODUCTION OF SMOKE AND THE LIKE 'Application filed January 11, 1927, Serial No.

This invention relates to a device for the production of smoke, odours and the like, which can be used for driving away or destroying insects and for curative, disinfect-ing and like purposes.

The devices of a similar kind known hitherto, in which, just as in the device according to the invention, a -combustion-point is arranged so as to be visible from al1 sides, have the dis- 10 advantage that the combustion point or a device for producing smoke is entirely or insuiiciently protected, so that, in the case of careless handling there is not only the danger of a fire being caused, but the device is difficult to handle owing to its becoming hot.

The known devices are for this reason not suitable to be used in rooms, hospitals or in verandas, on walking tours, when boating and the like, where they are frequently handled and are dangerous for the clothes and other readily combustible materials.

In addition it is relatively diiiicult to'attend to and to start the known fumigating devices. as in most cases they consist of a number of separate parts and the fuels used for producing the smoke have to be carried loose in separate vessels and containers.

The present invention obviates these drawbacks by a known fumigating candle bein used for producing the smoke, which is plac upright in a wire gauze protective container at a distance from the walls of the same and so as to be visible from al1 sides. The device provides absolute safety against danger of fire and can be kept under observation like other known devices to see if it is operating properly. The operation and manipulation of the device is extremely simple. Means are provided in accordance with the invention for causing the smoke produ-Ced to Whirl up in an effective manner and to be distributed to all sides in the surrounding atmosphere.

In the accompanying drawing constructional examples of the invention are shown by Y way of example.

Fig. 1 is a perspective view of a device constructed in accordance with the invention. Figs. 2-4 are perspective views in detail of three forms of the annular member closing the upper part of the device and the metal 160,466, and in Germany September 14, 1925.

cap associated therewith, these parts being removed from the cylindrical container.

A cylindrical container l, for instance of sheet metal, is provided with a bottom rim 2 and a top rim 3. The bottom rim 2 receives the bottom part 4 which is fixed in the bottom rim 2 by means of a bayonet catch arrangement 5. On the bottom part 4 is a holder 6 for receiving the fumigating candle 7. The top rim 3 of the container is connected to the bottom rim 2 by means of ribs 8. The intermediate space between the ribs 8 is filled with wire gauze 13. A metal cap 14 is provided for extinguishing the fumigating candle which is capable of being reversed and of acting as a conducting body for the smoke gases escaping from the fumigating candle, so that it can be Vmoved into the position 14. The cap 14 is located below an annular member 15 which closes the upper part 'of the device and in the position 14', forms a continuation of the wall of the member 15. The conical wall 16 ofthe metal cap provides with the wall l5 ari etlicient guide for the ascendingsmoke which is thereby forced to leave the device approximately horizontally in the direction and to be distributed to allsides. For reversing the metal cap a shaft l8'having a handle 19 or the like is provided. The shaft 18 may be so arranged that for the purpose of sliding it it is slightly withdrawn, its other end 20 being thereupon pushed through the wire gauze in the required position. The metal cap may thus be used as a heat intercepting Screen, for extinguishing the candle or as a distributor for the ascending smoke.

In Figures 2 to 4 various forms of the cap 14 and of the part of the upper rim adjoining the cap are shown.

For ensuring that the cap shall function properly and that the smoke shall thereby be effectively distributed and for increasin this eii'ect, for instance by preventing the interference of a lateral wind or current of air, a separate guiding member is provided for the air flowing to the point of combustion. In the constructional example shown this guiding member is formed by a sheet metal ring 21.

of the arrows 17 v What I claim is z` 1. A device for the production of smoke 'andthe like, vcomprising' in combination a. c lindricalcontainer, a bottom rim and a top rim for the said container, a transparent wire gauze covering, a umigating candle which is visible from all sides and is positioned in the device at a distance from the wire gauze covering, a bottom-part for the device, a holder for vthe fumigating candle, a cap for intercepting and distributing the ascending smoke and heat of the candle, and means for lowering the said cap onto the fumigating candle in the longitudinal direction of the candle onto the latter for the purpose of extinguishing it, as set forth. i

2. A device for the production of smoke and the like, comprising in combination a cylindrical container, a bottom rim and a top rim for the said container, connectingribs between the top and bottom rims, a transparent wire gauze covering, a fumigating ,candle which is Visible from all sides and is positioned in the device at a distance from the wire gauze covering, a bottom part for the device, said bottom part being connected with the bottom rim, a holder for the fumigating candle, a cap positioned above the fumigating candle, means for lowering the cap onto the candle for vextinguishing the same, means for inverting the cap, annular means at the top rim of the device, the inverted cap and the annular means together forming a guide for distributing the ascending smoke, and guiding means for preventing the smoke from being deflected laterally by wind or air currents before it reaches the top part of the device, as set forth. 7

In testimony whereof I have signed my name to this specification.
